Fig. 4, is a section on the line A box-like case 1 contains a vertically reciprocating knife 2, and forms a, chamber to hold the clippings detached from envelops in the course of the use to which the article is intended. The knife 2, is secured to a reci rocating plate 4 that engages between t e ends 5 and 6 of the case. At the rear of the reciprocating plate 4 is a hanging frame-bar 7 which hangs from the top plate 8, and

which is provided with seats 9, 10 and 11 for the reception of movable members 12, which bear against the back of the plate 4, and hold the knife 2, into close engagement with the front wall 13 of the case. The pressure members 12, are each pressed forward by a spring'14 inserted in t pressure member. The pressure member e cavity behind the carries on its front or protruding end an antifriction ball 15, restingin a seat in the pres-' sure member, and the actual contact is between the 'antifricti'on ball 15 and the back .of the plate 4.
